HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented April 2a, 1908.

Application filed February 24, 1903. Serial No. 144,557.

ers ada ted to vaporize a liquid and fluid to burn t ie resultant vapor;and it particularly relates to burners of this sort, which are used forheating the steam generators on automobiles, launches, traction engines,and the like.

In order that such burners shall be practically useful for suchpurposes, it is necessary to provide means for shutting off the mainburner, as wheri the automobile is to stand immovable for a while; andmeans for causing the automatic lighting of said burner when it isturned on, as when it is desired to run the automobile, and means,which, under all of the conditions incident to practical use, willvaporize an adequate quantity of the fuel without any such destructivedistillation of the latter as will cause carbon and other products ofsuch destructive distillation to be de ositedin said vaporizer, with theresult of c ogging it up and rendering in- 'eflicient to a greater orless-degree.

The invention may be here summarized as consisting in the constructionand combination of parts hereinafter described anddefinitely pointed outin the claims.

In the drawing, Figure 1 is a plan view of the burner and its associatedparts; Fig. 2 is a sectional elevation of the same; and Fig. 3 is a viewof the apparatus shown in Fig. 1, the view being in near said figure.

Referring to the parts by letters, A represents the main burner whichmay .be of any suitable specific construction. [The inlet to the mainburner is through a mixing tube a, which may be of the usual forrh.

"B represents a sub-burner: or pilot light which projects up through themain burner. This sub-burner may also be, of any suitable construction.

the direction of thearrow...

C represents avaporizer which lies partly over the main burner andpartly over the sub-burner, by which it is heated when the main burneris turned off. This vaporizer as shown in the drawing, is a castingcontaining a U-shaped passage indicated by dotted lines in Fig. 1. Theoutlet or discharge end of this vaporizer has a pipe 0 connected withit; and this pipe terminates in a nozzle 0 arranged to discharge intothe open end of the mining tube a. The inlet end of the vaporizer isconnected by a pipe F with the fuel supply tank (not shown). pipe F, isa valve casing D containing the main valve (1. This-casing also containsa second valve G; and the closin of either of these valves prevents theflow 0 fuel through the feed pipe into the vaporizer. This valve G is anautomatic valve, which, in the'construction shown, is lifted from itsseat by a bell crank lever K, and is moved to its seat by gravity orotherwise whenthe lever is allowed to move in the reverse direction.This bell crank lever is operated to lift the valve by a thermostat Nwhich extends into the generator. The generator, which is referably, butnot necessarily, used witi this Connected into this feed burner is thatwhich is shown in my prior patentNo. 659,837; and the tube J, in whichthe thermostat lies, is a part of this generator.

The specific means employed for causing the automatic operation of thevalve G is not at all material to the present invention. Such valves aresometimes operated by thermostats in the generator, and sometimes theyare operated by mechanism which is caused to operate by the pressure ofthe steam in the generator. Such devices are well known in this art, andit ls-of no consequence to this invention what .kind of automatic valve0 crating mechanism is employed, or w ether such mechanism is caused tooperate by the pressure or by the temperature of the steam. In fact, anyautomatic valve is not essential to the generic invention. It will benoticed that in the discharge ipe c of the generator there is no valve.T e part marked 0 is not a valve, ,but simply a movable plunger having apointed end which is designed to be moved off of either valve d or G insaid casing does not interfere with the flow of the fuel to saidsub-burner. The sub-burner is always light ed when the automobile isfired up; and therefore the apparatus is ready foroperation whenever themain burner valves are opened. Since this sub-burner is in heatingrelation'with the va orizer, the latter will be subjected to that eatinginfluence at all times whether or not the main burner is turned on. Ifthe fluid fuel were allowed to flow into this vaporizer and were heldtherein by some valve near its outlet end, this fuel, when so confined,would, after awhile, be heated to such a temperature by the subburner aswould result in a destructive dis-i tillation or cracking of the oil,and the con sequent deposition of carbon in the vaporizer. Very soon thevaporizer would become clogged up and practically useless. By thearrangement of parts, however,

'shown in the drawin and above described,

when either of the va ves G or d are shut off, not only is the supply tothe main burner cut ofi, but the supply of the liquid to the vaporizeris also cut oil. Such oil as may be between said valve and the dischargenozzle 0, when said valves are closed, will be vaporized and burned, butthereafter the vaporizer'will stand empty until the main burner valve isagain opened. Standing thus empty the vaporizer will be, heated, and sowhen the valves d and G are again opened, and the fluid fuel flows intothis hot vapo rizer, it will be immediately vaporized, and the vaporwill flow into the main burner. As it emerges from said'burner, it willbe lighted by the pilot light. The heat of the main burner willthereafter maintain the. necessary temperature of the vaporizer tovaporize the liquid fuel as it flows through it. Another advantage ofthe construction shown is that it permits the removal of the vaporizerfor the purpose of cleaning it, and its subsequent replacement.Obviously this would not be practical if the vaporizer remained filledwith the combustible fluid when the main burner were turned off. Theremoval of the vaporizer shown requires only the unscrewing of thesingle coupling nut by which the vaporizer supply pipe 0 is connectedwith the valve casin D. This being unscrewed the vaporizer, t e nozzle 0and the feed pipe 0 come out as a single piece.-

. To replace the vaporizer one inserts the boss therefor, a va orizerfeed pi e on. the inner end of said vaporizer into a hole in a fixedsupport P, and then screws on the coupling nut 9 The parts are then inreadiness for use. Having described my invention, I claim: 1. Thecombination of a main burner-having a mixing tube, a casing above themain her, wit 1 a feed pipe, a valve casing secured to said feed ipe, avaporizer feed pi'e which extends tliirough a hole in the we of thecombustion chamber and separably connects the vaporizerwith said. valvecasing, a valveless pipe connected with the discharge end of thevaporizer and extended out through the same hole in the wall of thecombustion chamber and terminating in a nozzle which discharges intosaid mixing tube, and an independent feed pipe for said. sub-burner,sub-- stantially as specified.
